-------------------------------------------------
> Query with a decimal between predicate needlessly fails
> -------------------------------------------------------
>
> Key: IMPALA-7211
> URL: https://issues.apache.org/jira/browse/IMPALA-7211
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 3.0
> Reporter: Taras Bobrovytsky
> Assignee: Taras Bobrovytsky
> Priority: Critical
> Labels: regression
>
> The following query causes an analysis exception because decimal(38,2) and
> decimal(38,3) are not compatible, i.e. it is not possible to cast them to the
> same decimal type without losing information.
> {code}
> select cast(1 as decimal(38,2)) between 0.9 * cast(1 as decimal(38,3)) and 3
> {code}
> However, if we rewrite the between predicate, it succeeds.
> {code}
> select cast(1 as decimal(38,2)) >= 0.9*cast(1 as decimal(38,3)) and cast(1 as
> decimal(38,2)) <= 3
> {code}
> Both queries should execute successfully.
